Simultaneous measurement of ventilation using tracer gas techniques and VOC concentrations in homes, garages and vehicles

This paper presents the development of an updated approach to determine simultaneously the effective air exchange rates (AERs) , the interzonal flows, and VOC concentrations over long and representative test periods. Those critical ventilation parameters affect thermal comfort, air migration and contaminant exposure in buildings and other environments. For the measurements perfluorocarbon tracer gas techniques (PFT), the constant injection rate method and adsorbent-based sampling of PFT concentrations were used.
